It is necessary for us to make traffic rules. Some traffic rules in some countries are quite unusual. Travellers should know these rules if they are planning to go to these countries by car.
Some unusual traffic rules are about animals. One strange traffic rule in Massachusetts, U. S. A. (美国玛莎诸塞州)says that people can take gorillas(大猩狸)to travel in a car. However, they can only ride in the passenger seat. Drivers will face a fine(罚金)if they let a gorilla ride in the backseat.
People like to take dogs in their cars in some countries. In Italy, rules ask drivers to fasten(系)their dog's seat belt when they take their dogs on a road trip. In Germany, although there is no safety belt rule, drivers must protect their pets against slipping and falling(滑倒)in the car.
In Austria, traffic police use their own feel to the the speed of a car. In this way, sometimes drivers may get a speeding ticket even if they are travelling under the speed limit(速度极限).
